INTRODUCTION 

 

The AMTI Gen 5 system allows you to connect and 
control AMTI force plates. The system works through a 
digital amplifier that collects the force plate data and 
transmits them to QTM in sync with the data being 
collected by the Qualisys camera system.  
 
This tutorial covers how to connect and begin using your 
AMTI Gen 5 system with your Qualisys camera system. 
For advanced settings beyond the scope of this tutorial, 
please refer to your QTM manual or to your AMTI documentation.
